JFE Engineering Corporation, a leading engineering company in Japan, announced on November 18, 2010, that it had successfully developed a breakthrough technology to capture and store carbon dioxide (CO2). The new technology can convert CO2 to CO2 hydrate under normal temperature and pressure, thereby reducing processing costs by half.
Conventionally, converting CO2 in water to CO2-hydrate, a sherbet-like solid compound, requires low temperature and high pressure conditions (e.g. 5 degrees Celsius at a pressure of 2.2 MPa or higher). The processing costs of this method, however, are very high, which has hampered its practical application.
